[PATCH v3 0/9] add --ff option to cherry-pick

[Christian Couder <chriscool@tuxfamily.org>]

The goal of this patch series is to make it possible for "git cherry-pick"
to fast forward instead of creating a new commit if the cherry picked commit
has the same parent as the one we are cherry-picking on.

The change since the previous series is that there is less refactoring
of builtin/revert.c before introducing the --ff option, so less code churn.
This also means that this series should be easier to merge.

Christian Couder (9):
  reset: refactor updating heads into a static function
  reset: refactor reseting in its own function
  reset: make reset function non static and declare it in "reset.h"
  revert: refactor checking parent in a check_parent() function
  revert: add --ff option to allow fast forward when cherry-picking
  cherry-pick: add tests for new --ff option
  Documentation: describe new cherry-pick --ff option
  cherry-pick: add a no-op --no-ff option to future proof scripts
  rebase -i: use new --ff cherry-pick option
